3 PAGE 3 of STATUS OF CONSTRUCTION / PROGRESS SUMMARY Progress Summary: 1. Continued the utility coordination with Washington Gas for the two 12-inch gas pipe risers at the North Pier abutment. Washington Gas delayed the previously scheduled completion date for the North Pier abutment to October 25, Washington Gas completed and evacuated the site, as scheduled, on October 25, Continued the utility coordination with Pepco along Water Street where the construction trailers were placed and mitigated the apparent conflict with the staging area. Continued efforts to setup coordination meeting with Pepco regarding site-related activities. Received information from Pepco regarding the onsite superintendent s contacts and invited them to the Key Bridge progress meetings. 3. Although contractor was given limited NTP for 45-days which started from September 27, 2016 and pending baseline schedule approval, we continued working on resubmittal of the baseline schedule and also provided contractor direct contact with the project team s schedule reviewer to enable them engage directly on on-going BL schedule build up issues. 4.

Continued to transmit RFI s and submittals to the appropriate discipline for review. 7. Continued to coordinate and facilitate meetings between NPS and Technopref for the special use permit so that Technopref can secure the NPS site, including access to the Potomac River, though staging preparations are currently ongoing. 8. Continued Constructability Review of Plans and site conditions to assist Technopref in any potential conflict resolution issues. 9. Continued to maintain project filing and document management systems (electronics). 10. Continued to maintain and manage the Project SharePoint. 11. Continued working with contractor and design engineer to compile lists of anticipated submittals. 12.

They indicate safety concerns as buses are forced to back up on Water Street as there is no place for them to turn around The location of the BID s construction dumpster is still a concern to the contractor Congestion and the mix of cyclists, vehicles and pedestrians continues to be a major issue PEPCO and DDOT coordination is still important as problems created by PEPCO's work may have negative repercussions for DDOT as opposed to PEPCO even though they (Pepco) may be at fault. 3.
